Section 1.1
What is Materials Science and Engineering?
The structure and composition of a material, including the type of atoms and their arrangement as viewed over the range of length scales (nano-, meso-, micro-, macro-scale). The properties of the material resulting from the atoms and their arrangement, that make material interesting or useful. The synthesis and processing by which the particular arrangement of atoms achieved. The performance of the material, that is, the measurement of its usefulness in actual conditions, taking account of economic and social costs and benefits.
